CapEX vs OpEX

CAPEX Model (Capital Expenditure):

• Buyer purchases the asset outright using capital funds
• Ownership immediately with buyer
• Buyer responsible for maintenance, consumables, and lifecycle management
• After warranty → Comprehensive Maintenance Contract (CMC) arranged separately
• Asset retained and disposed by buyer after useful life
• Expenditure = one-time (lump sum)

---

👉 Example: A Railway office buys 20 computers

• Full payment made at once
• Computers become Railway property
• After warranty → office arranges AMC/CMC (Annual/Comprehensive Maintenance Contract)
• Office purchases consumables (keyboard, mouse, parts, etc.)
• After 5–7 years → office disposes the computers

👉 Meaning: You own the asset and manage everything

—-------------------------------------------------------------------------------------------------

OPEX Model (Operational Expenditure):

• Seller provides the asset as a service (no upfront purchase)
• Ownership remains with seller
• Seller handles maintenance + consumables + performance
• After contract → asset taken back by seller
• Buyer does not handle disposal
• Expenditure = periodic / staggered payments

---

👉 Example: A Railway office hires 20 computers on contract

• No heavy upfront cost
• Monthly/quarterly rent paid
• Vendor provides maintenance + replacements + consumables
• After contract → vendor takes back computers

👉 Meaning: You just use the asset; vendor handles everything

GTKM vs NTKM

 

GTKM vs NTKM

Railway Terminology

GTKM (Gross Tonne Kilometre) 🚆

Standard Definition: Total weight of a train (including locomotive, wagons/coaches and payload) moved over one kilometre

It is a measure of total transport effort of Indian Railways

👉 Simple Practical Example:

Total train weight = 1,000 tonnes and Distance = 100 km

GTKM = 1,000 × 100 = 1,00,000 tonne-km

👉 Meaning: Railways use fuel, track capacity, and manpower to move entire train weight, not just goods

NTKM (Net Tonne Kilometre) 📦

Definition: Weight of only the paying load (goods/passengers) carried over one kilometre. It is a measure of earning output

👉 Simple Practical Example:

Goods weight = 600 tonnes and Distance = 100 km

NTKM = 600 × 100 = 60,000 tonne-km

👉 Meaning: Revenue is generated only from payload, not from engine or empty wagons

Key Difference (Exam Ready) 🎯

GTKM → Total weight moved (Effort)

NTKM → Paying load moved (Earnings)

Better Real-Life Analogy 🛻

A delivery truck travels 100 km

Total truck weight (vehicle + goods) = GTKM

Only goods inside the truck = NTKM

👉 Fuel is consumed for full truck weight (GTKM)

👉 Income comes from goods delivered (NTKM)

One Line Memory Trick 🧠

GTKM = Gross = Full train 

NTKM = Net = Only earning load

Block Account Vs Loan Account

Differences between Block Account & Loan Account 

Block Account - Assets created out of all sources of finance (Loan Capital + Internal Resources + RRSK + RSF)

Loan Account - Assets created out of Loan Capital only

Internal Audit - Differences with External Audit and Internal check - Chapter 9 of Finance Code

 

Internal Audit - Chapter 9 - Finance Code

Para 929. Internal Audit- Focus -Traditionally, the focus of internal audit has been on compliance of rules, regulations, policies and procedures. As is evident from the role assigned to the Internal Audit Wings in the “Redefined Charter for Financial Advisors” issued by Ministry of Finance on June 1, 2006, the remit of Internal Audit has been enlarged. While Compliance Audit remains important, internal auditors are now expected to focus on evaluation of controls with reference to the risks and to provide an assurance to the Management that the controls are functioning in the intended manner and hence there is a reasonable assurance that the goals and objectives of Ministry/Department will be achieved. Through this, Internal Audit contributes to the efforts to strengthen governance processes in Ministries/Departments.

Para 930. Internal Audit Process: The internal audit process comprises of five action phases. 1. Planning the audit engagement. 2. Preparing for Audit. 3. Performing the audit engagement. 4. Reporting upon the audit engagement; and 5. Follow up action. 931. A typical internal audit assignment involves the following steps: 1) Establish and communicate the scope and objectives for the audit to appropriate management/authorities. 2) Develop an understanding of the operational area under review. This includes objectives, measurements and key transaction types. This involves review of documents and interaction with the auditee. Flowcharts and narratives may be created if necessary. 3) Describe the risks facing the business activities within the scope of the audit. 4) Identify control procedures used to ensure each key risk and transaction type is properly controlled and monitored. 5) Develop and execute a risk based sampling and testing approach to determine whether the most important controls are operating as intended. 6) Report problems identified and review action plans with management to address the problems.7) Follow-up on reported findings at appropriate intervals for which Internal Audit departments must maintain a follow up database.

Para 932. Internal audit is a concurrent process and may not involve the detailed audit process, unless it is a specific theme based audit, undertaken as a special audit. By analyzing and recommending business improvements in critical areas, auditors help the organization to meet its objective. In addition to assessing business processes, Information Technology (IT), Auditors also review information controls.

Simplified Notes – Internal Audit

1. Focus of Internal Audit

• Traditional focus: Checking compliance with rules, regulations, policies, and procedures.
  Example: Ensuring Railway staff TA/DA claims are settled strictly as per rules.
  
  

• Redefined role (post June 1, 2006 – Ministry of Finance Charter):
  
  

• Go beyond compliance.
  
  

• Evaluate controls against risks.
  
  

• Provide assurance to management that controls are effective.
  
  

• Contribution: Strengthens governance processes in Ministries/Departments.
  Example: Internal Audit not only checks if railway procurement followed tender rules but also whether risks like inflated pricing or cartel formation are controlled.

2. Internal Audit Process (Five Phases)

1. Planning the audit engagement – define purpose, scope, and resources.
   
   

2. Preparing for audit – gather background, understand processes, meet auditees.
   
   

3. Performing audit engagement – conduct checks, risk analysis, and test controls.
   
   

4. Reporting audit engagement – document findings, suggest improvements.
   
   

5. Follow-up action – check if corrective measures are implemented.

---

3. Typical Steps in Internal Audit Assignment

• Define scope & objectives → communicate with management.
  
  

• Understand operational area → review objectives, documents, transactions; interact with auditee; prepare flowcharts if needed.
  Example: In Railway Stores Depot audit, study how issue/receipt registers are maintained.
  
  

• Identify risks → e.g., risk of material shortage, revenue leakage.
  
  

• Identify control procedures → systems to prevent/monitor risks.
  Example: Cross-verification of stock ledgers with physical stock.
  
  

• Test controls using risk-based sampling → check whether controls work effectively.
  
  

• Report problems & agree action plans → management reviews and corrective steps.
  
  

• Follow-up → maintain database of findings and ensure corrective action.

---

4. Nature of Internal Audit

• Concurrent process → runs alongside operations, not only after completion.
  Example: Checking contractor bills before payment, not after final settlement.
  
  

• Special audits → may be theme-based (e.g., “Audit of Passenger Refunds”).
  
  

---

5. Value Addition by Internal Audit

• Business process improvements – streamline systems and reduce inefficiency.
  
  

• IT & Information controls – ensure secure and reliable data management.
  Example: Verifying safety of Railway Passenger Reservation System (PRS) to prevent data manipulation.
  
  

• Assurance role – helps the organization achieve goals by improving risk management and control mechanisms.
